The Double Mountain Fork of the Brazos River is an ephemeral, sandy-braided stream heading on the Llano Estacado of West Texas about 18.5 km (11.5 mi) southeast of Tahoka, Texas. It is a tributary of the Brazos River, the longest river in Texas and the 11th longest in the United States.

The name comes from early Spanish explorers who christened the river Rio de los Brazos de Dios (meaning The River of the Arms of God). McCarthy uses the correct 19th century name for the tributary, which changed in 1964 to simply the Double Mountain Fork Brazos River.
